Corlar® 2.8 HG™
High Solids Epoxy
GENERAL
DESCRIPTION
A high build, high solids, two-component, VOC conforming (2.8 lbs./gal.), high gloss epoxy
based on Axalta modified polyamide epoxy technology. The resulting coating is designed to
be highly durable and to deliver outstanding corrosion and chemical resistance.
SUGGESTED USES
As a high performance coating or topcoat on properly prepared carbon steel, galvanized
steel, stainless steel, aluminum, concrete, concrete block and wood where:
 Smooth appearance with high gloss and custom color capability is desired.
 Excellent resistance to chemical and/or marine environments is required.
 Application by brush and roller, in addition to spraying, may be necessary.
 Application may be required down to 40°F.
USDA approved -- (incidental food contact) contains no lead or chromate pigments.
Corlar 2.8 HG will chalk upon exposure to sunlight. If gloss, color retention and color stability
are important, Corlar 2.8 HG should be topcoated with Imron® 2.8 HG™ or Imron 3.5 HG™
+ or other appropriate topcoat.
COMPATIBILITY WITH OTHER COATINGS
Corlar 2.8 HG is highly compatible with most coating types. It may be used over most aged
and hard cured coatings in good condition. Testing for lifting, bubbling and adhesion is
recommended to assure compatibility with unknown coatings. Contact your Axalta
representative for specific recommendations.
NOT RECOMMENDED FOR
 Immersion service
 Extreme exposure without topcoat

ACTIVATION
Thoroughly agitate Corlar 2.8 HG (26P) base to uniformly incorporate all pigments. Add 1
part Corlar VG-026 Activator to 1 part Corlar 2.8 HG (26P) base. Allow 1 hour induction prior
to using.
Reduction
None required for normal conditions. Use up to 20% T-8054™ Thinner on hot or windy days.
If more than 20% reduction is required, contact your local Axalta representative.

*Do not thin if compliance with 2.8 lbs/gal is required.
POT LIFE
5 hours @ 70°F to 90°F after induction period of 1 hour.
APPLICATION
SURFACE PREPARATION
Can be applied directly over properly cured primers or most old thermoset coatings in good
condition. Before application to surface, hardened or smooth concrete, roughen surface.
Surface must be clean, dry and free of chemical contamination.
APPLICATION CONDITIONS
Do not apply if material, substrate or ambient temperature is below 40°F (4°C) or above
110°F (43°C). The substrate must be at least 5°F (3°C) above the dew point. Relative
humidity should be below 90%.
ROLL APPLICATION
Manufacturer: Wooster® Pro/Doo-Z ¼"- ½" nap
 Keep roll wet. Roll in one direction, rewet, then cross roll.

Application Notes

Some colors may require multiple coats and higher film build to achieve complete hiding

Epoxies chalk with extended exposure to sunlight. Lack of ventilation, incomplete
mixing, mis-catalyzation or the use of heaters that emit carbon dioxide and carbon
monoxide during application and initial stages of curing may cause yellowing to occur.

SAFETY AND HANDLING
For industrial use only by professional, trained painters. Not for sale to or use by the general
public. Before using, read and follow all label and MSDS precautions. If mixed with other
components, mixture will have hazards of all components.
Ready to use paint materials containing isocyanates can cause irritation of the respiratory
organs and hypersensitive reactions. Asthma sufferers, those with allergies and anyone with
